OK, so this is the second mass knife attack this year with the other being on school grounds in China. I'm thinking it's time we have background checks before anyone can own or sell a knife! Where is the outrage over this unprovoked attack??

HOUSTON (KTRK) -- A stabbing attack on the Lone Star College Cy-Fair campus on Tuesday left more than a dozen people injured, but one suspect was taken into custody after quick-thinking students jumped into action.

The violence broke out at about 11:20am at the rear of the Health Sciences Building on the Cy-Fair campus on Barker Cypress Road.

Student Steven Maida said, "I didn't see him hit anybody, I just saw girl walk out with hole in her cheek. One girl had a hole in her neck, and this other guy had cuts on the back of the neck, and the other guy had a slice on the neck."

Without hesitation, Maida and several other students ran after the suspect.

James, a student at the school, told Eyewitness News he saw the suspect, dressed in black, emerge from the building at a run, and he gave chase. When tackled, the suspect reportedly said, 'I give up, I give up.'

"One kid grabbed him by the backpack, the other grabbed him by the arm, and the kid just said he gave up, and we just sat on him until the cops came," Maida said. "It was definitely an adrenalin rush. I wouldn't want to hear a girl die, especially if I could have done something about it."

No motive for the attack has been determined.

James says the suspect may be hearing impaired, and was armed with a knife similar to an exacto knife, that may be used in animal dissection labs. Officials have not confirmed the specific type of weapon used in the attacks.

Sheriff Adrian Garcia confirmed the suspect taken into custody was a 21-year-old student, described as a white male.

"We do not know exactly what type of weapon was used, other than to say at this point that it was some type of instrument," said Sheriff Garcia. "We don't know whether a knife or some other type instrument."

The Harris County Sheriff's Department confirmed there were 14 victims. Four patients were taken by Life Flight to Memorial Hermann Texas Trauma Institute and two more patients were transported by ground ambulance. The remainder were taken to North Cypress Hospital, and two people refused treatment at the scene. Two of the victims are listed in critical condition. North Cypress Hospital officials say all of the patients treated there had non-life threatning injuries and have since been released.

Students were held inside classrooms as the campus went into lockdown. One student told Eyewitness News he held a prayer circle with students in his classroom. Others were seen walking calmly to their vehicles in the parking lot. Deputies searched each vehicle before drivers were allowed to leave campus.

Cy-Fair ISD secured the following nearby campuses as a precaution: Aragon Middle, Postma Elementary, Fiest Elementary, Copeland Elementary, Birkes Elementary, Rennell Elementary, Robinson Elementary, Homesley Elementary, Jowell Elementary and The Berry Center. While the schools were not under an official lockdown, doors were locked and no visitors were allowed on campus.

Authorities say the investigation is an ongoing situation. They are reviewing video evidence and say the entire campus has been searched for evidence. There had been reports of a second suspect, but HCSO now confirms they believe the suspect acted alone and they have ended the search for any further suspects.

LSC-CyFair campus is closed for the remainder of the day/evening, but will reopen Wednesday morning. Counselors will be available to talk with students and employees and will be visiting the classes of those students who were victims as well. LSC-CyFair President Audre Levy also will also be holding debriefing sessions about the incident for faculty and students.

Rand Key, Sr. Vice Chancellor for Lone Star College system, said their thoughts and prayers are with those injured and their families.

Three people were injured in a shooting at the north campus of Lone Star College in January. The incidents are unrelated.

Police say they have detained a suspect, a 36-year-old man from the village, state media reported.

China was hit by a spate of knife and cleaver attacks that targeted school children in 2010.

A number of measures were introduced at the time, including increased security at schools across the country and a regulation requiring people to register with their national ID cards when buying large knives.
